Asked by Andrea
A sample of gold ore contains 22.0 g of gold metal per 100kg of ore. If gold has a market value of $350.00 per oz., what mass of ore, in tons, must be refined to get one million dollars worth of pure gold?

You want 1E6 dollars at $350/oz so you need 1E6/350 = ??ounces Au.
Convert ??ounces to grams (the problem doesn't specify Troy oz or Avoirdupois oz so you may need to ask). Multiply that by 100,000/22 because it isn't 100% gold in the ore,convert that to pounds then to tons. Post your work if you get stuck.
